For the past few years, iSkoot has been ensuring that these people can stay just as connected to their social network as their smartphone-carrying compadres with Kalaida, a cloud-based social network aggregator which OEMs and carriers can pre-load onto handsets before they hit the selves. Today, iSkoot’s announcing a new partnership with T-Mobile — and that with this recent momentum, Kalaida can now be found on over 100 different handset models.

T-Mobile will be using Kalaida to power their “Social Buzz” application, which brings basic support for Facebook, Myspace, and Twitter to handsets like the Samsung “:)”, Gravity 3, LG Sentio, and the upcoming LG dLite.

This isn’t iSkoot’s first carrier partnership, by any means. Kalaida can be found powering Verizon’s Social Beat, AT&T’s Social Net, and O2’s Social Link in the UK. Managing to get one carrier to throw your wares onto a bunch of handsets is no small feat — but four major carriers? Consider us impressed.
